String Algorithms and Data Structures Laboratory

String Data Processing LaboratoryMembers : Prof. Shunsuke Inenaga / Assoc.Prof. Yuto Nakashima

keywords : Algorithms, Data structures, Data Compression, Combinatorics on Words, Theoretical Computer Science

Strings are concepts that generalize sequential data such as text, time series, labeled trees/graphs, and 2D arrays. Our research interests are in designing fast and space-efficient algorithms for processing strings, with particular emphasis on their theoretical perspectives. Since the discovery of classical algorithms including KMP, suffix trees, and LZ compression, string algorithmics has been one of the most important sub-fields in theoretical computer science. Also in the real world, string algorithms are commonly utilized as core building blocks of information retrieval systems and data compression programs. Further, string-related problems are commonly seen in competitive programming contests. Our approach for tackling massive sequential data is first to reveal mathematical properties of strings using the theory of “word combinatorics”, and then to develop advanced “algorithms and data structures” techniques.

Information Security & Multimedia Security LaboratoryMembers : Prof. Kouichi Sakurai / Asst.Prof. Wissam Razouk

keywords : Network Security, Security Camera, Security Robot, Adversarial Machine Learning, Computer Security, Cryptography

Nowadays, not only people but things are getting increasingly interconnected in what is called Internet of Things (IoT). In a world where almost everything is connected, if an attacker gets control of one of these networks it can be disastrous. Attacks can go as far as changing the election results of a country (USA’s 2016 election was strongly influenced by Russian cyberattacks). Moreover, in a recent report from Forbes, cybercrime is projected to reach 2 trillion dollars by 2019. To protect society, we research new technologies and paradigms for security related applications.

Laboratory of Intelligent Systems

Laboratory of Intelligent SystemsMembers : Assoc.Prof. Danilo Vasconcellos Vargas

keywords : Deep Learning, Neuroevolution, Action/Image Recognition, Multi-agent based Intelligence, Bioinspired Artificial Intelligence, Artificial General Intelligence, Evolutionary Computation, Reinforcement Learning, Adversarial Machine Learning

In the Laboratory of Intelligent Systems we create novel AI engines as well as build robust and adaptive intelligent systems. Current AIs can solve 19×19 versions of Go but behave poorly on easier 9×9 versions of the same game. Similarly, image recognition algorithms can reach 96% accuracy (supra-human) on tests and be fooled by only one pixel change. In other words, current AI lacks the robustness and adaptation present in even simple living beings. AI is based on engines that allows it to learn and reason over things, this lab builds novel engines based on different paradigms to reach high levels of robustness and adaptiveness intrinsically. Interestingly, by increasing the robustness and adaptiveness, other problems like Transfer Learning, One-Shot Learning would also be solved at the same time, igniting, possibly, a new age of intelligent systems.

We focus particularly on the relationship between quantum information theory and nonequilibrium statistical physics, combining the conceptual frameworks and mathematical techniques of both fields to analyze a wide range of phenomena.

Our primary interests lie in two broad questions: the fundamental limits inherent in physical processes, such as thermodynamic transformations, measurement processes, and computation; and the extent to which quantum effects can modify or overcome these limits. Because these themes span both foundational and applied aspects of physics, our group actively explores both directions.

On the foundational side, we investigate topics such as universal constraints on quantum dynamics arising from symmetry. On the applied side, we study quantum-mechanical mechanisms for realizing heat engines that surpass classical power bounds while approaching Carnot efficiency. Through these efforts, our laboratory aims to deepen the theoretical understanding of quantum-enhanced physical processes and to contribute to future quantum technologies.

Pattern recognition is a research field that focuses on the artificial realization of the human cognitive system. It is still difficult even though computers are highly developed today. For example, we humans can easily recognize a car at a glance as “That is a car.” However, there are numerous models in cars, and appearance will change depending on a point of view even if we look at the same model. The easiest way to handle this issue is to classify the input based on the similarity to patterns stored in a computer in advance, but challenges remain such as the definition of similarity. The key point is how to handle variety in patterns that causes difficulty. In this laboratory, we develop pattern recognition techniques and the related applications such as image processing/recognition, bioimage informatics, machine learning, and character engineering/science. We are challenging these attractive problems with our unique techniques and competing against the world.
